Options to get stuff shipped from China...Lets discuss

hello, I was going to make my first purchase from sunsky..
which option is better for shipping from sunsky? the cheapest options shown are "epacket" and "yanwen express", with the former being a bit cheaper

and.. the website is "sunsky-online.com" right? just confirming because its being referred to as just 'sunsky' here
Lot of people here are saying that shipping via yanwen doesn't attract customs but it's upto you
 
If I'm to get a mini pc from China, what would be the customs cost?
No one can tell, but the maximum customs cost can be half the total cost of your product, but the twist is, depending upon the custom officer, if he think that the actual value of item is more than what you have paid or listed, he will use his own imaginary value that he sees fit and then the maximum customs can be half of that.

This is the worst case scenario.
